Figure 10 is Figure 8 is a sectional schematic diagram at B-B in

[0032] In some embodiments, as Figures 1-6 and Figures 8-10As shown, the loudspeaker in the embodiment includes a first connecting portion 1, a second connecting portion 2, a yoke 3, a magnetic assembly 4, a vibrating portion 5, and two mounting portions 6. The vibrating portion 5 includes a diaphragm 51 and a voice coil 52 fixedly connected with the diaphragm 51. The yoke 3 includes a receiving groove 31, a connecting window 32, and a side window 33 in communication with the receiving groove 31. The diaphragm 51 is fixedly connected with the yoke 3 to cover the connecting window 32. The side window 33 is located below the connecting window 32 and faces a side of the connecting window 32. The magnetic assembly 4 is arranged on the yoke 3. The magnetic assembly 4 is attracted to a bottom of the yoke 3. The magnetic assembly 4 generates a magnetic force acting on the yoke 3, and a magnetic gap 43 is formed between the yoke 3 and the magnetic assembly 4. At least a part of the voice coil 52 is located in the magnetic gap 43. The first connecting portion 1 includes a first connecting end 11 and a second connecting end 12. The first connecting end 11 is electrically connected with the voice coil 52. The second connecting end 12 extends from the side window 33. The voice coil 52 is electrically connected with a circuit board outside the loudspeaker through the second connecting end 12. The mounting portion 6 is used to block the side window 33. The second connecting end 12 is fixedly connected with the mounting portion 6, and at least a part of the second connecting end 12 is exposed outside the mounting portion 6. The mounting portion 6 can prevent sound leakage, and the mounting portion 6 is used to fix the second connecting end 12.

[0033] Optionally, the yoke 3 is made of metal, such as steel, iron, iron-based alloy, cobalt-based alloy, or the like. The mounting portion 6 is made of organic polymer material, such as plastic, rubber, or the like. Under the action of the magnetic assembly 4, the yoke 3 can better play a role of magnetic conduction to guide the magnetic field to act in the magnetic gap 43. The mounting portion 6 has good insulation and injection properties, and can be injection molded according to the shape of the side window 33 to better block the side window 33, while avoiding short circuit with the second connecting portion 2.

[0034] In summary, the loudspeaker in the embodiment is provided with the receiving groove 31, the connecting window 32, and the side window 33 on the yoke 3. The first connecting end 11 is electrically connected with the voice coil 52, and the second connecting end 12 extends from the side window 33. The magnetic assembly 4 arranged in the receiving groove 31 can form the magnetic gap 43 with the receiving groove 31. Thus, the diaphragm 51 is covered on the connecting window 32, and the mounting portion 6 is blocked on the side window 33, so that the receiving groove 31, the diaphragm 51, and the mounting portion 6 form a sound chamber, the volume of the sound chamber is increased, and the sound quality is improved. On the other hand, the yoke 3 is configured as a magnetic conductor, so that the yoke 3 participates in the magnetic circuit, thereby reducing the volume occupied by the loudspeaker and reducing the number of components of the loudspeaker. On the other hand, the connecting window 32 and the side window 33 are spaced apart, so that the sealing performance of the diaphragm 51 and the mounting portion 6 is better, and sound leakage is effectively prevented. In addition, the mounting portion 6 is also used to fix the second connecting end 12, so as to facilitate the connection of the second connecting end 12 with the control circuit outside the loudspeaker.

[0035] In some embodiments, as Figure 3 , Figure 4 ,Figure 6 and Figure 9 As shown in FIG. 1, the yoke 3 comprises a magnetic conducting bowl 34 and a magnetic conducting frame 35. The magnetic conducting frame 35 is arranged on the magnetic conducting bowl 34 and forms the accommodating groove 31 and the side window 33 with the magnetic conducting bowl 34. The magnetic conducting frame 35 comprises a magnetic conducting flange 351 and the connecting window 32. The magnetic conducting flange 351 extends to the magnetic assembly 4 and forms the magnetic gap 43 with the magnetic assembly 4. The yoke 3 in the embodiment is designed in a split manner. The diaphragm 51 can be fixed to the magnetic conducting frame 35 first, and then the magnetic conducting bowl 34 is fixed to the magnetic conducting frame 35 by welding. Thus, the installation mode of the loudspeaker is simplified.

[0036] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 9 , the magnetic assembly 4 comprises a first magnetic part 41. The magnetic conducting bowl 34 comprises a bottom plate 341 and a side plate 342. The side plate 342 is connected to the plate edge of the bottom plate 341, and the side plate 342 is folded towards the diaphragm 51 and forms a first recess 343 with the bottom plate 341. The first magnetic part 41 is arranged on the bottom plate 341 and spaced apart from the side plate 342. At least part of the plate edge of the side plate 342 overlaps the magnetic conducting frame 35. The magnetic conducting bowl 34 in the embodiment can be made by stamping. The first recess 343 is used to accommodate the voice coil 52, the magnetic assembly 4 and at least part of the magnetic conducting frame 35.

[0037] In some embodiments, as shown in Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10 , the magnetic conducting frame 35 comprises a first plate body 352 and a second plate body 353. The first plate body 352 surrounds the first magnetic part 41 and one side edge forms the magnetic conducting flange 351. The second plate body 353 surrounds the center of the diaphragm 51 and forms the connecting window 32. In the axial cross-sectional direction of the voice coil 52, the second plate body 353 is located outside the first plate body 352. The first plate body 352 in the embodiment can optimize the magnetic field distribution of the magnetic gap 43, so that the magnetic field lines in the magnetic gap 43 are more concentrated.

[0038] In some embodiments, as shown in Figure 4 , Figure 5 , Figure 9 and Figure 10 , the first plate body 352 and the second plate body 353 are arranged in a spaced apart manner. The magnetic conducting frame 35 further comprises a third plate body 354. The third plate body 354 is annular, and one plate edge of the third plate body 354 is connected to the outer edge of the first plate body 352, and the other plate edge is connected to the inner edge of the second plate body 353. The plate edge of the side plate 342 away from the bottom plate 341 overlaps the plate surface of the third plate body 354 away from the first plate body 352.

[0039] Specifically, asFigure 5 As shown, the magnetic conducting frame 35 in the embodiment is in a ring structure, and the cross-sectional profile of the ring structure in the extending direction is in a Z shape. The third plate body 354 forms an avoiding space close to the inner side region of the voice coil 52, and the first plate body 352 corresponds to the folded ring of the diaphragm 51 close to one side of the diaphragm 51. When the diaphragm 51 is recessed towards the sound chamber, the avoiding space can avoid the diaphragm 51, preventing the folded ring from contacting the frame 3.

[0040] In some embodiments, as shown in Figure 5 and Figure 10 , the extending direction of the first plate body 352 and the second plate body 353 is perpendicular to the axial direction of the voice coil 52, and the extending direction of the third plate body 354 is parallel to the axial direction of the voice coil 52. The first plate body 352 and the third plate body 354 are located in the first groove 343, and the second plate body 353 abuts against the plate edge of the side plate 342.

[0041] The magnetic conducting frame 35 in the embodiment is hung on the top of the magnetic conducting bowl 34 through the side plate 342, so as to increase the contact area with the side plate 342 through the third plate body 354 and the second plate body 353, so that the magnetic force generated by the magnetic assembly 4 can be more uniformly conducted to the magnetic conducting flange 351. At the same time, the cooperation of the side plate 342 and the second plate body 353 can limit the height position of the magnetic conducting frame 35. The cooperation of the side plate 342 and the third plate body 354 can limit the position of the magnetic conducting frame 35 in the horizontal direction.

[0042] In some embodiments, as shown in Figure 3 , Figure 5 , Figure 9 and Figure 10 , the first magnetic part 41 includes a first magnet 411 and a first magnetic conducting plate 412. The first magnet 411 is adsorbed between the first magnetic conducting plate 412 and the bottom plate 341, the first magnet 411 is located in the middle of the first plate body 352, and the plate edge of the first magnetic conducting plate 412 is arranged opposite to the magnetic conducting flange 351 and forms a magnetic gap 43.

[0043] Specifically, the thickness and height of the first magnetic conducting plate 412 are consistent with the thickness and height of the first plate body 352, so that the magnetic force lines of the magnetic gap 43 can pass through the voice coil 52 more densely. The ampere force of the voice coil 52 is optimized.

[0044] In some embodiments, as shown in Figure 4 and Figure 9As shown, the third plate body 354 includes two first segments 3541 and two second segments 3542 in the length direction. The first segments 3541 extend along a straight line and are located between the two second segments 3542. The length of the first segments 3541 is greater than that of the second segments 3542. The side plate 342 includes two first side plates 3421, which are located on both sides of the two first segments 3541 and abut the plate surfaces of the two first segments 3541, respectively.

[0045] Specifically, in the thickness direction of the first side plate 3421, the two first side plates 3421 clamp the magnetic conduction yoke 35 to position the magnetic conduction yoke 35 in this direction. At the same time, the contact area between the first side plate 3421 and the magnetic conduction yoke 35 is increased to optimize the magnetic field distribution on the magnetic conduction yoke 35.

[0046] In some embodiments, as shown in Figure 4 and Figure 9 As shown, the third plate body 354 further includes four curved segments 3543 in the length direction, and the first segments 3541 and the second segments 3542 are connected through the curved segments 3543.

[0047] Optionally, the first segments 3541 and the second segments 3542 extend along a straight line. In the direction of the axial cross section of the voice coil 52, the inner side surface profile of the magnetic conduction flange 351 is a rounded rectangle.

[0048] Further referring to Figure 6 As shown, the side plate 342 further includes two second side plates 3422, which are located between the two first side plates 3421 and have both ends bent and connected to the first side plates 3421. The second side plates 3422 are spaced apart from the magnetic conduction yoke 35. The plate edges of the second side plates 3422, the plate edges of the second plate body 353, and the first side plates 3421 form the side window 33.

[0049] Optionally, the second connecting end 12 is first fixedly connected to the mounting portion 6, and then the mounting portion 6 and the second connecting end 12 are fixed to the top of the second side plate 3422. In this form, the magnetic conduction yoke 35 is fixed to the top of the magnetic conduction bowl 34, and the magnetic conduction yoke 35 is fixed to the mounting portion 6, so that the magnetic conduction yoke 35 and the second side plate 3422 clamp the mounting portion 6. In turn, the sealing performance of the mounting portion 6 to the side window 33 is improved.

[0050] In some embodiments, as shown in Figures 8-9As shown, the first side plate 3421 has a notch 3423, which is recessed from the edge of the first side plate 3421 away from the bottom plate 341 towards the bottom plate 341. The two notches 3423 are arranged opposite to each other and penetrate through the side plate 342. The magnetic assembly 4 also includes two second magnetic parts 42 located in the receiving groove 31. The two second magnetic parts 42 are respectively disposed in the two notches 3423 and abut against the magnetic cup 34. The second magnetic parts 42 can be bonded to the magnetic cup 34 with an adhesive, so that the magnetic force of the second magnetic parts 42 acts on the magnetic cup 34.

[0051] In this embodiment, the two second magnetic parts 42 are used in conjunction with the first magnetic part 41 to provide magnetic force for the magnetic gap 43. At the same time, the notch 3423 corresponding to the second magnetic part 42 can optimize the distribution of the magnetic field generated by the magnetic component 4 on the frame 3, and prevent the magnetic force generated by the first magnetic part 41 from interfering with the magnetic force of the second magnetic part 42 through the first side plate 3421.

[0052] In some implementations, such as Figures 9-10 As shown, the second magnetic part 42 extends along the length direction of the notch 3423. One side of the second magnetic part 42 abuts against the first plate 352, and the other side abuts against the bottom plate 341. In this embodiment, the second magnetic part 42 can further optimize the magnetic force distribution of the magnetically conductive flange 351.

[0053] In some implementations, such as Figure 9 As shown, the first side plate 3421 includes two fourth plates 3424 and a fifth plate 3425. The fifth plate 3425 is located between the two fourth plates 3424, and the height of the fifth plate 3425 is less than that of the fourth plates 3424. A notch 3423 is formed between the fifth plate 3425 and the opposite side of the two fourth plates 3424. The second side plate 3422 is connected to the fourth plates 3424. The second magnetic part 42 abuts against both the two fourth plates 3424 and the fifth plate 3425.

[0054] Specifically, the second magnetic part 42 is a magnetic block, the bottom of the side of the magnetic block abuts against the fifth plate 3425, and both ends of the magnetic block abut against the fourth plate 3424. This increases the magnetic force on the first side plate 3421.

[0055] Figure 11 This is an exploded view of the first connecting part 1, the second connecting part 2, the second magnetic part 42, the magnetic guide frame 35, and the mounting part 6 provided in the second embodiment.

[0056] In some implementations, such as Figures 9-11As shown, the two fourth plate bodies 3424 abut the two ends of the first section 3541, and the middle region of the first section 3541 corresponds to the gap 3423. The width of the first plate body 352 is the same as the width of the second magnetic part 42. In this way, the contact area of the second magnetic part 42 and the magnetic conducting frame 35 is increased, and the magnetic force distribution acting on the magnetic conducting flange 351 is optimized.

[0057] In some embodiments, as shown in Figure 6 As shown, the mounting part 6 has a first positioning surface 61, a second positioning surface 62, and a third positioning surface 63. The first positioning surface 61 and the second positioning surface 62 are opposite to each other. The first positioning surface 61 abuts the plate surface of the second plate body 353, the second positioning surface 62 abuts the plate edge of the second side plate 3422, and the third positioning surface 63 abuts the plate edge of the first side plate 3421. In this embodiment, the first positioning surface 61, the second positioning surface 62, and the third positioning surface 63 can be bonded by an adhesive. At the same time, the sealing performance of the mounting part 6 on the side window 33 is improved.

[0058] In some embodiments, as shown in Figures 3-4 and Figure 9 As shown, the mounting part 6 further has two mounting surfaces 64 which are spaced apart. The mounting surface 64 is adjacent to the second positioning surface 62 and is away from the second side plate 3422 relative to the second positioning surface 62. The first connecting part 1 is a flexible circuit board which includes two first connecting ends 11, two second connecting ends 12, a fixed region 13, and a deformation region 14. The voice coil 52 includes a coil body 521 and two lead wires 522 connected to the coil body 521. The fixed region 13 is fixedly connected to the coil body 521. The two lead wires 522 are electrically connected to the two first connecting ends 11, respectively. The two second connecting ends 12 are arranged on the two mounting surfaces 64, respectively.

[0059] During the movement of the voice coil 52, the deformation region 14 can generate a reset elastic force to drive the diaphragm 51 to quickly reset. In the axial direction of the voice coil 52, the height difference between the mounting surface 64 and the second positioning surface 62 is configured to be equal to the thickness of the second connecting end 12. When the second positioning surface 62 abuts the second side plate 3422, the second connecting end 12 abuts the plate edge of the second side plate 3422. In this way, after the mounting part 6 blocks the side window 33, a gap is avoided between the second connecting end 12 and the second side plate 3422, and the sound leakage is reduced.

[0060] Figure 7 FIG. 1 is an exploded schematic view of the first connecting part 1, the second connecting part 2, the magnetic conducting frame 35, and the mounting part 6 provided in the first embodiment.

[0061] In some embodiments, as shown in Figure 6 , Figure 7 and Figure 11As shown, the mounting portion 6 includes two pads 65 and a blocking strip 66. The pad 65 has a mounting surface 64. The blocking strip 66 includes a third segment 661 and two fourth segments 662. The third segment 661 is located between the two fourth segments 662, and the third segment 661 is attached to the board surface of the second segment 3542 away from the voice coil 52. The fourth segments 662 are curved, and the two fourth segments 662 are respectively attached to the board surface of the two curved segments 3543 away from the voice coil 52. The two pads 65 are respectively protruded on the side of the two fourth segments 662 close to the magnetic yoke 35, and the side of the pad 65 away from the mounting surface 64 is in abutment with the board surface of the first board 352 away from the second board 353. In the length direction of the first segment 3541, the mounting portion 6 is wrapped around the two sides of the magnetic yoke 35 in the embodiment, so as to position the magnetic yoke 35 by the two mounting portions 6.

[0062] In some embodiments, as shown in Figure 3 and Figure 8 As shown, the bottom plate 341 has a vent hole 3411, and the vent hole 3411 is in communication with the accommodating groove 31. The loudspeaker further includes a vent patch 36, and the vent patch 36 is attached to the hole edge of the vent hole 3411 toward or away from the accommodating groove 31.

[0063] Specifically, the vent patch 36 in the embodiment is attached to the hole edge of the vent hole 3411 away from the accommodating groove 31. That is, the vent patch 36 is attached to the outer surface of the bottom plate 341. In this way, dust can be prevented from entering the sound chamber. At the same time, the vent hole 3411 makes the sound chamber in communication with the outside of the loudspeaker, and effectively avoids the pressure change in the sound chamber when the volume of the sound chamber changes due to the vibration of the diaphragm 51, thereby affecting the deformation of the diaphragm 51.

[0064] In some embodiments, as shown in Figure 2 and Figure 4 As shown, the second connecting end 12 has a contact 121 away from the mounting surface 64. One second side plate 3422 has two second grooves 3426 corresponding to the two contacts 121, and the second grooves 3426 extend along the axial direction of the voice coil 52 and are recessed toward the voice coil 52. In the cross-sectional direction of the axial direction of the voice coil 52, at least part of the contact 121 is located inside the corresponding second groove 3426. The second groove 3426 in the embodiment is used to avoid the contact 121, so as to facilitate the connection of the control circuit and the contact 121.

[0065] In some embodiments, as shown in Figure 3 and Figure 11As shown, the first connecting part 1 and the second connecting part 2 are both flexible circuit boards, and the first connecting part 1 and the second connecting part 2 are identical in form, that is, the second connecting part 2 comprises the fixed area 13, the deformation area 14, the first connecting end 11 and the second connecting end 12, and the first connecting part 1 and the second connecting part 2 are symmetrically arranged. However, the second connecting part 2 does not have to be electrically connected with the voice coil 52. Thus, the deformation amplitudes of the first connecting part 1 and the second connecting part 2 are consistent, and the force on the voice coil 52 is balanced.

[0066] Further, as shown in Figure 4 and Figure 9 , the two first connecting ends 11 are fixedly connected with the end surface of the voice coil 52 away from the diaphragm 51. Thus, in the static state, the diaphragm 51, the first connecting part 1 and the second connecting part 2 are in the same plane.

[0067] In an alternative implementation, the loudspeaker in the above embodiment can be applied to an electronic device. The electronic device includes but is not limited to a mobile phone, a computer or a wearable device, etc.

[0068] In summary, the electronic device in the embodiment has the yoke 3 provided with the accommodating groove 31, the connecting window 32 and the side window 33. The first connecting end 11 is electrically connected with the voice coil 52, and the second connecting end 12 extends out of the side window 33. The magnetic assembly 4 arranged in the accommodating groove 31 can form a magnetic gap 43 with the accommodating groove 31. Thus, the diaphragm 51 is capped by the connecting window 32, and the mounting part 6 is sealed by the side window 33, so that the accommodating groove 31 forms an acoustic chamber with the diaphragm 51 and the mounting part 6, the volume of the acoustic chamber is increased, and the sound quality is improved. On the other hand, the yoke 3 is configured as a magnetic conductor, so that the yoke 3 participates in the magnetic circuit, thereby reducing the volume occupied by the loudspeaker and reducing the number of components of the loudspeaker. On the other hand, the connecting window 32 is spaced apart from the side window 33, so that the sealing of the diaphragm 51 and the mounting part 6 is better, and the sound leakage is effectively prevented. In addition, the mounting part 6 is also used to fix the second connecting end 12, so as to connect the second connecting end 12 with the control circuit outside the loudspeaker.

[0069] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
